Installing an RPM file on AIX 4.3.3

I have an RPM file that I'd like to install on a system running AIX 4.3.3. I select Install Software Bundle (Easy Install). After supplying the source directory path, I select Media Defined. When I try to select the Software to install, I get the following error:

0503-003 installp: The specified device /tmp/RSYNC is not a valid device or file.
